Yes, we slowly develop this way of bypassing the lateral force of the piston .. here, that's all you have to do is one lever that has a half-ring at the end, but the other way round. This way one pulls up and the other down during the movement of the lever ... It can be used for a full four-stroke engine .. Well, see how easy we can cool the water piston ..

A traditional crosshead, usually unbalanced, to save a little on the construction .. But for this, when the command "whole back" is taken for the ship's engine, only 60% of the power can actually be used, because of this unsymmetrical crosshead, which can not withstand greater load, in the reverse than usual turnover.
In my solution, it does not matter which engine the engine is on, so "the whole back" can actually be "all", i.e. 100% ..

But in my solution, it may be asymmetrically, for the same reason as in the traditional one, it means that the piston is pressed down all the time, if not by the work stroke, then by the compression stroke ... (of course, it is 2 stroke ) .. Therefore, the second lower frame, can be "symbolic" and the thin line, just to keep the kinematic bond in some abnormal situations.
Of course, all this new mechanism can be in a separate housing, separating the oiled space, from the space under the piston, which can be cooled water ..
Developing further ideas for smaller engines, instead of a rope, we can use a toothed belt, whose durability is known from the mechanisms of timing .. But the revolutions can be a little bigger ..

http://www.dtic.mil/dtic/tr/fulltext/u2/821500.pdf Here is a handbook, but it is very long uploading, because 35 MB .. On the 74 page, such a two-stroke engine, whose piston pin, is a ball, which moves only pressure from above in a pristine way ..

Well, there is one big advantage of such a crosshead. We can freely change the stroke, piston in relation to the crankshaft stroke .. For example, the stroke of the piston is the same, and the crankshaft stroke even twice as long .. Everything will depend on the demand, and what is most important in a given engine application ..
Of course, the rope has to go exactly in the axis of the piston ..

So that his way of placing the crankshaft, as you can see in the figure, from the side, will make the engine will be much lower ..
Of course, only for marine engines 102 rpm

The film shows that with 3 movements of the arm, the vehicle travels about 10 meters .. with a piston stroke of 50 cm, having 300 cubic centimeters of air, a liter will travel 30 meters .. from 100 liters 3 km, and from a pressure of 200 atmospheres 60 km. .. 10 such tanks, and we have a range of 600 km .. 100-liter tank is a pipe with a diameter of 24 cm and a length of 2 meters in a square meter will fit 16 such tanks .. ie in the tank 1 m x 1 m x 2 m, 200 atm, it we have a range of 1000km ... I am wrong somewhere, because through my miastenia , I have a double vision .. Such an idea for a Polish family-owned electromobile car .. And it is with us (Poland) REAL, most importantly ..
No Tesla ..

with a simple and light, cheap engine, pneumatic cylinder .. Just 3 cm in diameter, if the pressure is 10 atmospheres ..

Well, this is my new idea ... I decided to get rid of force, guide the piston ...
This gives an average of about 10% higher efficiency of the engine, because we do not waste energy on friction .. In marine, eolnobrotowych, so far used to be used crosshed.
Instead, I used such a machanism, based on oil like a pump, with a rope as a working element .. Because the rope can not be "pushed", I put the other such arm in motion to the other side .. And from this simple connecting rod driving the crankshaft. Thanks to this, there is no side force anywhere in the whole mechanism .. It is in a traditional design, very large force, reaching up to 1/6 of the total force in the connecting rod driving the crankshaft .. Here its size is calculated .. I think that the average 10% of the engine's reliability will be obtained. The engine has very small orots, 100 rows per minute, and I think that this will work ... In the steam locomotive, we will get rid of the slider, and its efficiency will increase significantly ..
Certainly the demand for oil, which suppressed this large friction, will be much smaller ..
Maybe someday it will go to F1

So I have to thank that good people brought me to the ground with my Segway Car Felix ... I of course have invented it completely unmistakably, never seen such a solution .. But I was provided with my much earlier (2011) professional Segway rules here a few photos.

Al sure in this company you did not see the veturi nozzle of my idea. Put on the luggage of the car such a tube with a diameter of the meter, in the middle of a real turbine and at 40 km / h we have an additional 100 hp .. And now what?

Or maybe a two-wheel car would do ... There's no need for an differential and anything .. see the Segway
There is no steering wheel, and what's the return .. because let's say on wheels 1.5 meters in diameter ... for every trimmer will come ..

Such a Segway with a comfortable seat and visor, it could be called Feliks Car
